Custom DNA Oligonucleotides


Our oligos are synthesized with a typical coupling efficiency of 99% and purified by QPC free ofcharge. PAGE purification is also available with additional charge. The high coupling efficiency of our synthesis technology allows efficient synthesis of oligos up to 120 bases. In addition, a variety of modifications are available. Every oligo is analyzed by PAGE to check oligo quality. Malidi-Tof Mass QC is also employed to examine the oligos randomly at our facility.
